Ontario researching name for lake

Jan 17, 2018 | Communications | General | Public Notice

The Ministry of Natural Resources and Forestry (MNRF) through the Ontario Geographic Names Board has received a request to officially name the lake on the east side of Orangeville as Island Lake. The board is conducting a survey of local residents and businesses to determine local usage and the existence of other names associated with the lake. The lake is still being shown on mapping systems, such as Google, ESRI, and Bing, as “Orangeville Reservoir” while the lake has been known locally as Island Lake for years. The board will collect feedback and forward a recommendation to the Minister of Natural Resources and Forestry for final approval, in accordance with the Ontario Geographic Names Board Act. If the name change is approved the lake will then be recorded on mapping resources as Island Lake.

A questionnaire is posted at You can comment on the proposed name request by completing the questionnaire by February 1, 2018. The board is interested in hearing if there is a different local name in widespread use and if there is support for the proposed name.

If a hard copy of the questionnaire is desired, please print out a copy from the website. Submit a completed questionnaire online, by email or print and fax to 705-755-2149 or print and mail to:

Formerly known as Orangeville Reservoir Conservation Area, Island Lake Conservation Area was created with the construction of two dams by Credit Valley Conservation in 1967. The reservoir was designed to maintain water quality and quantity through controlled outflows into the Credit River and to provide a recreational resource.

The small body of water that preceded the damming and flooding by Credit Valley Conservation was called Island’s Lake. In 1977, Credit Valley Conservation endorsed changing the name to Islands Bay but that didn’t find much support and so the name Orangeville Reservoir was used. In 1992, the Town of Orangeville recommended the name change to Islands Lake Conservation Area and in 1994 the conservation board agreed. In 1997, coinciding with the launch of a management plan, the property was renamed Island Lake Conservation Area in recognition of the Island family who had previously owned and farmed the land.
